Language of Muscles: A Strategy for Learning
Kevin Patton: The fitness guru and television personality Jack LaLanne once said, “If you’ve got a big gut and you start doing sit ups, you’re going to get bigger because you build up the muscle. You’ve got to get rid of that fat. How do you get rid of fat? By changing your diet.”
Aileen: Welcome to the A&P Professor, a few minutes to focus on teaching human anatomy and physiology with host Kevin Patton.
Kevin Patton: In this episode, we’ll have updates regarding the cerebellum, liver and body weight, then a discussion of how understanding muscle names helps students learn.
Kevin Patton: For a long time we’ve all been teaching that the cerebellum’s job is to help coordinate muscle movements. Scientists first learned this when we saw that when the cerebellum is damaged, it impairs the process of planning and executing a variety of body movements. Now calm down, neuroscientists are still on board with this story. However, over the last few decades we’ve seen at least two changes to the last, best story of the functions of the cerebellum.
Kevin Patton: One is that we’re learning a lot more about all the complex mechanisms involved in how the cerebellum functions in partnership with the cerebrum to plan and execute movements. For example, some recent experimentation is showing that the cerebellum has a big impact on memory, specifically the memory needed for effective motor planning. That makes sense, right, because as we learn a movement like how to bat a tomato thrown at us by a student out of the air before it splats on our face, we have to try and fail a few times before we’re good at it. Each time we try that movement, we remember or our cerebellum cerebrum team remembers each exact instruction involved in the motor programming.
Kevin Patton: When we bat at that next thrown rotten tomato, we probably do a little better because our cerebellum is making corrections based on the memory of what happened the last time. A few more rotten tomatoes and we can bat them out of the air accurately every single time, giving it barely a thought. At least I can. That’s because I’ve had a lot of practice. That’s because the cerebellum is using memories of failures to adjust the motor programs that coordinate our movements.
Kevin Patton: These recent experiments I mentioned are confirming that the cerebellum is somehow involved directly in the memory activity, not simply getting the memories from the cerebrum. This is a bit more than we’d been giving the cerebellum credit for, right? There’s also some evidence that this carries through to slower, more thought out movements. That is, movements that require consideration and strategizing like moving chess pieces around on a chessboard. I don’t think we can support that idea fully at this point but this is where the science is taking us, so stay tuned.
Kevin Patton: Another thing that’s been going on with our evolving story of the cerebellum is that, well, it’s not just for coordinating movements. Think about it. The cerebellum has somewhere around half the total number of neurons in the brain. Yeah, motor coordination is going to need a lot of neural processing, but maybe it’s not so surprising that there’s more going on in there too with all those neurons.
Kevin Patton: Over the last few decades, we’ve seen a variety of additional cerebellar functions demonstrated. For example, it seems to have roles in abstract reasoning, in regulation of emotions, in social interactions, in our brain’s rewards system, all kinds of things. We’ve also seen that besides direct communication with the motor cortex, the cerebellum also communicates directly with other areas of the cortex, with the cerebral nuclei or basal ganglia if you prefer that, and connections with nuclei in the midbrain and other areas of the brain.
Kevin Patton: Because of these discoveries, we’re now learning more about the possible additional mechanisms involved in things like addiction, autism and even decision making. What’s becoming clear is that the cerebellum has a wider range of function than we used to realize. Our last, best story is getting more and more accurate. How do we handle that in our A&P course?
Kevin Patton: One way is to pay attention to what each new edition of our textbooks are saying. They’re gradually evolving their stories to keep up. What I do is use an analogy, one that fits well with the linkage between the names and functions of the cerebrum and cerebellum. Remember that cerebrum means brain and cerebellum means little brain, so it’s like the cerebellum is a sidekick to the cerebrum in a way.
Kevin Patton: I tell my students that it might be useful to think about the cerebellum as the, oh, I don’t know, the executive assistant to the cerebrum, a sort of chief of staff always in communication with the cerebrum but also in communication with other parts of the brain, coordinating a wide variety of functions and perhaps even doing a bit of decision making.
Kevin Patton: As time goes by, that analogy may give way to a better one as we learn more about the cerebellum. It’s just a matter of what the next last, best story of the cerebellum will be.

Liver Responds to Food Stimuli
Kevin Patton: We all know that seeing food, hearing about food, talking about food, like donuts for example or apple fritters for example as I’m doing right now, can trigger a set of neural and hormonal responses that get our digestive tract ready for that food, for those donuts. Just in case those donuts I’m thinking about right now actually appear in my hand and then get eaten. Then my saliva will be ready, waiting to great that donut, and my stomach will have some gastric juice waiting too. That rumbling I feel? Oh yeah, the stomach is getting in too, it’s churning up some donut [inaudible 00:07:38], right?
Kevin Patton: Well, a study that came out a few months ago is suggesting that there’s a lot more going on than we thought. It seems that darn donut is also triggering some neurons that signal the liver. Neurons that we used to think only kicked in later on after a meal or at least later in a meal, a meal of donuts and apple fritters in this case. These neurons, called POMC neurons, signal sympathetic pathways to the liver to get things ready for what happens after the meal. That is, to get ready to deal with the nutrients absorbed into the blood after a meal.
Kevin Patton: The hepatic cells in response start switching on genes, making proteins and expanding their endoplasmic reticulum in anticipation of all the work the liver will be doing during the absorptive state after a meal to deal with the carbs and fats and so on that we’re getting from our meal of donuts.
Kevin Patton: We’re not just getting ready for the first part of dealing with a meal. We’re also getting ready for the storing the nutrients stage that happens after a meal. All just because you saw some donuts in the window of a donut shop.

Exercise, Diet, Metabolism, & Body Weight
Kevin Patton: Honestly, I’m very hesitant to bring up this next topic because it’s a real can of worms. Not only are there controversial aspects that can profoundly affect the lives of individuals and the choices they make and the attitudes they have, but it’s something that we science educators think we know something about but we don’t really know much at all. It’s something that scientists working in this area don’t know much about either even though it sounds like they know what they’re talking about.
Kevin Patton: What topic is it? It’s the relationship of exercise, diet, metabolism and body weight. Yeah, that. Once you get me started talking about almost any topic it’s hard to shut me up, but this topic especially. If you’re listening to this episode and it’s less than three hours long, that means I must have gone back and edited out most of what I said.
Kevin Patton: What got me to thinking about this topic is that I once again noticed the usual flow of the confusing, incomplete and sometimes contradictory articles about exercise, diet, metabolism and body weight, and also the fact that this week I had my annual physical during which my doctor congratulated me on the fact that my body mass index or BMI is not in the obese range, yay, unlike most of his other male patients my age.
Kevin Patton: One of the articles I ran across recently talks about some research that seems to show that exercising more won’t help you burn more calories. As soon as I read that headline, I stepped off my treadmill to finish the article which describes a study on hunter gatherers who apparently hunt and gather all day long but don’t burn any more calories than a typical western commuter who goes into work to sit at a desk all day. Why? Well, because our bodies adapt. It’s not a simple matter of exercise more, burn more calories, there all kinds of genetic, metabolic, hormonal, neural and possibly even magical things that are happening in our bodies to regulate our internal environments in ways that maintain longterm stability. No matter what we’re doing or not doing today or this week.
Kevin Patton: Another article I ran across deals with the notion that healthy, thin people have faster metabolic rates than average. This is a common notion, right? Well, a recent study seems to debunk this idea and instead give more weight, forgive the pun, gives more weight to genetics. That is, maybe thin people who seem to maintain a low weight even when they do or don’t do the things that make me gain weight, they don’t have a different metabolic rate than me overall. Maybe they just don’t have the genes that are telling my body to store more fat and turn my six pack into a keg.
Kevin Patton: Study after study is turning our ideas about the relationship of exercise, diet, metabolism and body weight upside down and inside out and then back again. How do we, as A&P teachers, deal with it?
Kevin Patton: The answer is, I don’t know. I mean really, that’s my answer, but come on, I have to have some kind of answer, right? I can’t just skip over that part of my course, can I? I’m here to tell you, yes, you can, but I don’t suggest that. No, please, do not skip over that part of your course.
Kevin Patton: I will tell you what I do. I’m not saying it’s the best thing to do but I’m just sharing what I do and you can do with that what you want. I simply tell my students that we’re entering into an area where the story is not very clear yet. That while I usually try to stick to the last, best story about any topic we cover, maybe it’s useful to recognize that the best I can do is tell them the last, conflicted, muddy story. You know, the kind of story you get in the occasional novel in which nothing gets resolved, nothing comes together and you’re just left sitting there scratching your head and wondering why you just spent 20 hours slogging through this story?
Kevin Patton: I stick to the mainstream story, all the while pointing out that it’s all being questioned right now. Yes, some folks think that body mass index is an important health indicator and represents something important and that includes nearly all primary care providers these days, but maybe it’s not. Students need to know about it because they’re going to encounter it. We can’t let them out of our course not knowing what BMI is or what it represents or how it’s calculated or how it’s used, but they also need to know that this part of the story will likely change soon. It is changing already. Perhaps it will be completely ripped out of the story before too long, but right now they need to know what it is.
Kevin Patton: Yeah, some folks still think that counting the calorie intake listed for different foods we eat and the burned calories listed for the exercises we do are the beginning and end of the story of body weight and metabolism. We should be aware of that concept because people are using it, but we should also mention that this is a far from complete picture of what’s happening in our bodies. There are all kinds of footnotes to it.
Kevin Patton: I can’t say that the number of calories my diet book lists for this donut I’m about to eat will actually be available to my cells for use or storage. I can’t say that the miles I walk or stairs I climb today will burn X number of calories in my body today. I can’t even say that my fitness tracker is really reporting my overall activity in any kind of useful way.
Kevin Patton: I give them the basics. Throw in some questions and challenges and then I step back and marvel at how complex the real story of our body metabolism must really be and how fascinating it is to continue to follow the experimentation and debates and fistfights as scientists slowly unravel and then knit back together and then unravel again the full and true story.
Kevin Patton: Of course, the upside to the existing deep mysteries of the relationship of exercise, diet, metabolism and body weight is that I can expect to have reasonable success with my new book called Kevin’s Walking-Slowly-Then-Sitting-Down Donut Diet without anyone having much of a chance of challenging it with scientific evidence. As a matter of fact, I can probably find a whole bunch of articles that would support a central idea like that. Look for it on Amazon or your favorite bookseller starting next week.

Featured: Language of Muscles: A Strategy for Learning
Kevin Patton: Learning muscles is hard for most A&P students. There’s a lot to learn and students can be intimidated, so they’re not exactly starting off on the right track. One thing that intimidates them is the oddness of muscle names. Now yeah, it’s true they know a few partial names like biceps, quads, hamstrings, traps, slats, but even so, they know only a few and the name they know really has no specific meaning for them.
Kevin Patton: What about the term lat describes that muscle? Okay, maybe once they think about it, already having learned some basic anatomy in our course, they can work out that lat and lateral are connected and maybe they can figure it out from there, but how far does just a few of those really get us?
Kevin Patton: An idea I’ve alluded to before is that the language of A&P is important. At least that’s my perspective, and when I’m teaching my class, well, it’s my class and that’s where I take it. It’s worked pretty well for my students and for me as an anatomy learner, and this is my podcast so that’s where I’m going to take it, at least for this discussion.
Kevin Patton: If I visit an area of the world where the language is unfamiliar to me, and I’ve done that, it seems even more foreign in a lot of different ways and it’s pretty intimidating trying to get around or just find some lunch. If I have at least some familiarity with the language, then I feel more comfortable and I do much better navigating my way in a new place in a new culture.
Kevin Patton: One of the first things I tell my students starting a class with me is try to familiarize yourself with the language of each new topic as one of your first steps before even starting to dive into that new topic. That process, that approach, that attitude works especially well with muscles, I think.
Kevin Patton: Why does it work so well with muscles? Well, because the name of a muscle often tells you a lot about that muscle that makes it different from other muscles. I mean that’s how it got its name after all, right? It was named for some characteristic that that muscle has, but if you’re not paying attention to the name and just hearing it as an odd combination of syllables and leaving it at that, it’s going to be harder to learn. That weird name, that huge collection of weird names, becomes an unnecessary barrier to learning all about muscles.
Kevin Patton: Something else about this approach to learning muscles is that if you pay attention to the meaning of the names, that in itself becomes a mnemonic device, right? A mnemonic device is a memory aid and if you know the meaning of a muscle name, that automatically becomes a way of remembering at least the characteristic for which the muscle was named. If you remember that an extensor muscle extends apart and you’re looking at the upper extremity, you can at least figure out which side of the forearm to look at to try and find that muscle.
Kevin Patton: As with any mnemonic device, if you can remember any little thing about the object you’re trying to remember, that little thing usually triggers the rest of the memories you have about that thing. Remembering that one thing about an extensor muscle is likely to give you everything you need by triggering that part of your memory bank, making retrieval easier for you.
Kevin Patton: What I’m saying is that muscles have their own built in mnemonic triggers that our students often don’t know about and therefore it can’t help them. I’m encouraging us to go ahead and tell our students about this and get them started looking at muscle names that way, as helps rather than hindrances. Now I know what’s going through your head right now, “Hm, okay, how exactly would I do that in my course with my students?” Well I can’t answer that for you but I can tell you how I do it and that might spark some ideas.
Kevin Patton: As always, when your ideas get sparked or when you realize you’ve been doing this all along but in a different way than I do it, I invite you to share that with our other listeners. Just call the podcast hotline and tell us about it. As I’ve said, the first thing I do is way back at the beginning of the course, I tell them how important the meanings, the translations of terms in A&P really are. I encourage them to pay attention to that. If I keep reminding them at intervals, then it won’t seem so odd when we get to muscles and I bring it up again.
Kevin Patton: Then when we start muscles, I make sure that I have a couple of muscle models or at least a big torso model that has lots of big muscles visible, they’re with me, and an articulated skeleton, that’s helpful too. Then I throw out a couple of muscle names that are easy to translate. For example, abductor magnus. Then I tell them that it’s in the thigh and I ask them what might help us find it?
Kevin Patton: For example, I might ask them what does an adductor do and we can talk about what adduction is. Then I might ask them which side of the thigh would it have to be on to do that? That gets them thinking about how muscles work, that they’re pulling on parts of the skeleton and so on. Then I ask them what does magnus mean? Well, that’s similar to its meaning in English, right? We eventually get to, maybe with a little prodding sometimes, that it means great, so which of these medial thigh muscles is greater than the others? I kind of lead them along a little bit, kind of a logical progression there so then you start to see how helpful the muscle name is.
Kevin Patton: Or another example might be pectoralis major. Pec means chest which I might have to tease out of them. Maybe sometimes I’ll say, “Does anybody know where the pectoral fins in a fish are?” That will lead them to the chest area. Then the major part, well, that’s easy because again that’s similar to what’s in English. Then I point out the pectoralis minor to contrast with the pectoralis major and we’re starting to get it even more now. Of course, I have to make sure that I have a model that’s going to show a pectoralis minor on it in order for that to work.
Kevin Patton: Then I mention a couple of principles that will help them. The first one is their Latin. Well, of course their Latin. All these terms that we use in A&P are Latin, but what it means with muscle names is they’re going to all have Latin endings and there’s a large variety of Latin endings. Those endings may help somebody figure out whether that word is a noun or an adjective form, but it’s the root that we’re mainly interested in. That’s what I encourage my students to focus on, is the root of that word.
Kevin Patton: Speaking of nouns and adjectives, there are some things that might help clarify the naming of muscles. Keep in mind that in Latin the noun generally comes first and the adjective modifying it comes next. That’s the opposite of English. In English we might say, “little red wagon,” but in Latin we’d say, “wagon red little.”
Kevin Patton: The primary noun in all muscle names is the word muscle. Muscle is part of the name but we often skip that, especially when we’re studying muscles, exploring muscles, we just leave that off because we already know what we’re talking about. This is an area where we usually mix up the Latin and English format or syntax, so when we’re anglicizing the term we kind of flip it around. If we use the pure Latin format or Latin syntax, then muscle goes first. Actually if we’re really sticking to the pure Latin, we wouldn’t use the word muscle, we’d use musculi or musculus, but we do usually anglicize it so we put the word muscle last. It would be sartorius muscle.
Kevin Patton: Also, we often abbreviate the muscle. If we’re going to use it at all, we often abbreviate it as either a capital M or a small M, sometimes with a period after it, sometimes not, but we usually just skip it entirely and leave off the word muscle. Because, hey, we’re talking about muscles already and we don’t really need to keep saying muscle, muscle, muscle.
Kevin Patton: At this point I usually mention that we do the very same thing with bones, which they will have just studied before getting to the muscle module in my course. I point to the frontal bone on the skeleton that I said I usually have with me and I ask what’s the name of this bone? They say frontal, but I tell them that’s not the name of the bone. What’s the name of the bone? Then they get frustrated with me and I point out that the name of the bone is frontal bone, not frontal, it’s frontal bone. Frontal is an adjective that means nothing without a noun to modify it.
Kevin Patton: It’s like if I said I lost my yellow. How would anyone know that I meant my pencil? It could be my submarine that I lost for all they know. If I’m talking about bones, it’s okay to just call it frontal, so that’s what we did when we studied the skeleton. We called this frontal and that maxillary and this parietal and so on. If I’m sitting there working in my coloring book with a big pile of pencils and I say I’ve lost my yellow, that’s okay too because now you know that I’m talking about my pencil. It’s context that can contribute to the meaning of what we say. Of course we know that but here’s a place where it particularly applies to using anatomical terminology.
Kevin Patton: Now I don’t tell them this to go all Alex Trebek on them and tell them they forgot to put their answer in the form of a question or some other little technicality that makes their answer unacceptable, but I do it to simply let them know how to communicate professionally and accurate and that it’s sometimes okay to use a partial name for something and sometimes that’s just not clear enough to use a partial name. That is, I’m going to emphasize to them that they ought to be aware of the rules of the game.
Kevin Patton: Getting back to muscle names. Muscle is the noun, even if it’s not there and is merely implied by the fact that we’re exploring muscles. However, some muscle names do appear to be nouns and not adjectives describing a noun. For example, sartorius. Sartorius literally means tailor and tailor is a noun, right? In this case, it’s used as an adjective.
Kevin Patton: Really, it’s sartorius muscle because remember, muscle is part of the name, so it’s the sartorius muscle, not just the sartorius. If we were talking about the sartorius outside the context of anatomy and outside the context of looking at muscles and we talked about the sartorius, we really could mean a literal person who sews clothing. Since we’re talking about muscles, we can just use sartorius as a shorthand form of the full name, sartorius muscle. We would translate that as tailor muscle.
Kevin Patton: Here the noun, tailor, is used as an adjective. It’s describing the muscle. What kind of muscle? It’s a tailor muscle. It’s like when I use my teacher voice. Teacher is normally a noun but I’m using it as an adjective to describe the loud enough, clearly enunciated voice I use when I’m in the classroom. You know, that voice we forget to use in a faculty meeting so that people other than those just around us can hear what we’re saying?
Kevin Patton: Again, I don’t think most students will need to know all of that, but it is good for us to know that if for no other reason than to help those students who really embrace this method and want to dive deeper into it. Or in case we’re competing in the A&P tournament on Jeopardy.
Kevin Patton: I then point out some groups of muscle naming characteristics. Like names that have to do with the size of a muscle, like major and minor and longus and brevis and magnus and minimus and vastus and so on. Or names that have to do with the shape of a muscle like trapezius and orbicularis and rhomboid and serratus and gracilis which translates as slender. Or maybe the number of heads that a muscle has like biceps and triceps and quadriceps. Or the direction of the fibers within a muscle organ like rectus or oblique or transversus. Or maybe the action of the muscle like adductor or flexor or extensor.
Kevin Patton: Or the attachments of that muscle to the skeleton. For example, one of my favorites, sternocleidomastoid, just because I like the way that sounded. It has a lot of syllables and just kind of rolls off the tongue. Sternocleidomastoid.
Kevin Patton: Or I mentioned those that have particular unique characteristics like the sartorius that I just mentioned, the tailor muscle, or the lumbricals which are the worm muscles. Or the masseter which is the chewer muscle, or the buccinator which is the trumpeter muscle. Once you know those names, you often don’t forget them because they evoke an image, an image of a shape or a size or a trumpeter. That’s what makes them good as mnemonic devices. They really lock it into our memory, or at least lock it in a little bit better than it’d be locked in otherwise.
Kevin Patton: Some A&P books give lists or tables or other kinds of helps along these lines so that it’s pretty handy for students that are using this kind of approach. Then after that, I give them a few more examples so they can see what I’m doing.
Kevin Patton: Okay, once again, I know what you’re thinking. How are my students going to be able to do this on their own? Well, maybe they can’t. That’s okay. I just want them to know where the names come from and that they do have a meaning that could help them. If they pay attention, maybe they can simply figure out some of them and use the name to their advantage for learning. I use a textbook that has most of the muscle names translated for them, if not in the chapter word lists then in the glossary.
Kevin Patton: To make it easier for students, I give them a handout that lists the translation of each muscle name. You’re welcome to use my handout. I have a link to it in the show notes and episode page. The link takes you to my Lion Den web site where you have to register and it’s free, don’t worry about that. You register for it, put in your email and choose a password. You can download either the PDF or DOCX format.

Kevin Patton: The handout also has pronunciation guides for each muscle name too. I just updated it a few days ago, so if you’ve downloaded it before you may want to do that again so you have the latest version. I also have links to resources that you can point students to from your own course. You don’t have to do any of this in your class. You can have them use the video or web pages on their own instead. As always, if you have some additional tips along these lines or have reasons why you think this approach may not be a good idea, then let us know.

Preview of Episode 40
Kevin Patton: Hi there. This is Kevin Patton with a brief audio introduction to episode number 40 of The A&P Professor podcast, also known as TAPP Radio, an audio jamboree for teachers of human anatomy and physiology.
Kevin Patton: The upcoming full episode is all about eponyms. The good, the bad, and the ugly. Yes, it’s The Eponym Episode. It’s all eponyms all the time. Meaning that it’s the only topic I’m covering in that episode.
Kevin Patton: So what are eponyms? Okay. They’re terms named after people. But why are eponyms going out of style? How should we best deal with them in our A&P teaching? Well, that topic and more, on episode number 40 of the A&P Professor podcast.

Kevin Patton: Hey, I have some more dissections, and the first one is one you probably would have guessed. Yes, it’s eponym. And if we break that apart, it tells us exactly what it means. Epo-, the first part, means upon. And the last part, -nym, means name. So, it literally means upon a name, or really, name upon. And it’s a term that’s named after a person. So an example would be, the loop of Henle, that’s named after Friedrich Henle, a Bavarian anatomist and physician who discovered the loop of Henle. Actually, he has at least ten structures found all over the body named after him. So, that name Henle doesn’t really tell you much about where exactly it is or what it is, does it? And there are so many different things named Henle, I’m not so sure this eponym thing is a good idea. But I’m going to talk more about that in the full episode.
Kevin Patton: Our next term is an eponym. It’s Haversian canal. And I know that most of you pronounce that ha-VERS-ian canal, or ha-ver-see-an canal. And I’ll explain in a moment why I prefer HA-vers-ian. But let’s break it apart first. Havers, the first part, is where the name comes in. It’s named after Clopton Havers, an English physician who had a real strong interest in osteology. He discovered a number of structures within bone tissue, including the haversian canal. The -ian ending, which is the end of the term Haversian, means relating to. We’ve seen that frequently, right? And then, canal means, canal, or tube, or river, or whatever. So put it all together, and we have a tube named after Clopton Havers. And now that you know who it’s named after, I think you can see why I prefer the pronunciation of HA-vers-ian rather than ha-VERS-ian. Because he didn’t pronounce his name Clopton Ha-VERS. It was Clopton HAV-ers. So, HA-vers-ian rather than ha-VERS-ian. But, it’s up to you.
Kevin Patton: Another term that I want to dissect before we leave this segment is toponym. And that’s a term, I don’t know, I don’t hear that very much when we’re talking about anatomical and scientific terminology. But we use toponyms a lot. So let’s break it apart and then talk about what it is. Topo- is a word part that means place. -nym, we already mentioned, means name. So, it’s named for a place rather than for a person. So, toponyms are similar to eponyms. But they’re named for a place rather than a person. For example, Lyme disease. That’s a toponym, because it’s named for a town in Connecticut. Not a person named Lyme. It’s a town in Connecticut where the condition was first identified. In anatomy and medical circles, toponyms are often lumped together with eponyms. And I do that too. So in the full episode, or if you ever run into me on the street and we start talking about eponyms, keep that in mind.

Kevin Patton: This podcast is sponsored by HAPS, The Human Anatomy and Physiology Society, promoting excellence in the teaching of Human Anatomy and Physiology for over 30 years. Go visit HAPS at theAPprofessor.org/haps. H-A-P-S. And maybe I’ll see you at the HAPS Southern Regional in Louisville next week.
Kevin Patton: Yup, I have another recommendation from The A&P Professor Book Club. This time it’s a book called The Secret Language of Anatomy. Ooh, that sounds mysterious, doesn’t it? It’s by Cecilia Brassett, Emily Evans, Isla Fay, with a foreword by Alice Roberts. This book, The Secret Language of Anatomy, has been described as an initiation into the mysterious subject of anatomical terminology. Yeah, it is. I think our students would really get a kick out of this book. But so do I.
Kevin Patton: So it’s really not just for the uninitiated. I think even we A&P teachers will not only enjoy it, but also look at the whole idea of anatomical terminology in new and deeper ways. Ways that will rush in and improve our teaching. So what exactly is this little book? Well, first, it is little. Way smaller than that A&P book laying on your desk there. Wait. This is a podcast. You may not be at your desk. Okay, it’s smaller than the big A&P textbook on your dashboard. In your backpack. Or, I don’t know, inserted as an extra weight into your home gym machine. I don’t know.
Kevin Patton: But mainly, it’s a collection of drawings that uncover the close relationships between the parts of the human body and the evocative names given to them by anatomists. Decoding the body’s secret language brings to life the history of anatomical terms, and explains why some words are used to describe very different organs and structures. For example, there’s a page with a drawing of the heart with the atria labeled, alongside a sketch with a building’s floor plan with an atrium labeled. And there’s the tectorial membrane of the inner ear alongside a sketch of a tectum. That is, a roof.
Kevin Patton: Okay, don’t get me started. There’s page after page of these things, and it’s fun flipping through it. This is a cool book that should be on every A&P teacher’s desk. Or on your dashboard, or whatever. Not just because it’s fun for us, but I think it’d be a great teaching tool as well.
